Tainan

Source identity and administrative path

The source row behind Tainan is GeoNames ID 1668355. Its recorded administrative path is Tainan → Taiwan, and GeoNames classifies the place as a second-order administrative seat.

Tainan occurs once as a primary city label in this atlas sample; the numeric ID remains the durable source key if names change. The city row itself was updated 2025-11-06; that date belongs to the source record, not to every transport or visitor detail in the real destination.

Population position inside fixed cohorts

Within the fixed 1,206-record atlas, Tainan ranks 227 by recorded population. Inside the 6 selected Taiwan entries it ranks 5; inside the 632 entries in its broad region it ranks 135.

Its 1,856,642 population value is 0.66 times the 2,793,973 median for the country cohort and 1.84 times the 1,008,426 regional median. Tainan is rank 5 among the 6 selected Taiwan entries, so a percentage band would overstate this small cohort.

Tainan's recorded value is materially below the country-cohort median used here. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.

Nearest-reference pattern

Tainan's three nearest other atlas coordinates are Kaohsiung at 42.893 km with 2,737,660 recorded people; Taichung at 137.204 km with 2,850,285 recorded people; Banqiao District at 258.54 km with 551,221 recorded people. The closest-to-farthest distance spread is 215.647 km. Compared with Kaohsiung, Tainan's recorded population is 0.68 times as large. Against Tainan, Kaohsiung follows Kaohsiung → Takao → Taiwan in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Taiwan cohort, uses the shared Asia/Taipei identifier, and carries first-order administrative seat rather than second-order administrative seat.

Its recorded population is above Tainan's. Against Tainan, Taichung follows Taichung City → Taiwan in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Taiwan cohort, uses the shared Asia/Taipei identifier, and carries the same second-order administrative seat class. Its recorded population is above Tainan's. Against Tainan, Banqiao District follows New Taipei City → Taipei → Taiwan in the source.

Its point has higher latitude and higher longitude; it belongs to the same selected Taiwan cohort, uses the shared Asia/Taipei identifier, and carries the same second-order administrative seat class. Its recorded population is below Tainan's. Its nearest-neighbor distance ranks 379 of 1,206 from shortest to longest in the same snapshot. Tainan's nearest-coordinate gap sits in the second quarter of atlas distances. This pattern can reveal whether other catalog references are geographically close, but it cannot establish whether a border crossing is possible or practical, or whether rail, road, fare, or journey-time connections exist.

Read as one record signature, GeoNames 1668355, the coordinate pair 22.9908 / 120.2133, country rank 5 of 6, and neighbor GeoNames 1673820 at 42.893 km bind Tainan to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.

Coordinate, time-zone and class cohorts

Tainan's reference point is 22.9908° north and 120.2133° east. The IANA identifier Asia/Taipei is shared by 6 city rows in this catalog, while the GeoNames class PPLA2 is shared by 341 rows. Tainan's row carries both second- and first-order administrative labels.

Tainan's point falls in the lower-latitude coordinate band used by this atlas's row checks. Tainan's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Tainan, so the profile preserves that missing value instead of guessing terrain.

Together these fields form a reproducible identity check for this page, not a claim about walkability, climate or accessibility.
